Yun has nasty cross up roundhouse divekicks and medium divekicks. Here’s a fucked up mix up that will destroy shoto players.
Do your bread & butter combo with a medium upkicks as an ender (strong, strong, strong xx upkicks).
Hold Neutral jump and do medium divekick. if they quick rise and you time it right, it gets a nasty cross up that can’t even be DP’d.
IF THEY DON"T QUICK RISE, it gets even nastier. Your medium divekick will whiff, you hold up AGAIN and do a somewhat-delayed roundhouse divekick. it hits deep and you can follow up after with stand jab-stand strong into medium upkicks again. The cross up will look weird and you’ll be super far but it does combo and it looks amazing. Its really strong and i’ve been hitting it against most of the locals around here in nor-cal. Let me know if it works out for you guys.
I think Ken VS Yun is slightly in Kens favor because he has the get out of jail free card with his fierce shoryu game (and he keeps his meter if he hit confirms the first 2 hits of shoryu). But Yun has tricks against ken also, like whiff punishing his whiffed step kicks and putting him in cross up situations where KEN can’t DP. So it’s not too bad, but still tough for Yun in my opinion.
